I need to monitor network traffic and EtherApe seems to be nice graphical utility. But the Wikipedia entry says sth like this :
EtherApe requires root privileges to run. As such, there can be risks to the machine(s) running EtherApe when connected to the internet.
I am not getting this , we need to be connected to internet to monitor it, we do not need it at all if we are offline , don't we ?
If there is security risk what it could be and how to use it properly ?
